im having 3 issues: 1- I fly my rocket, everything is fine, then if I revert the flight, the same rocket will crash a few meters from the launchpad. I noticed that in theses cases, monopropellent is used even b4 launch once autopilot is engaged. I have to close and reload the whole game. Its like mechjeb still think its in space with the other rocket or something like that. 2- I sent a vessel to Duna but when it left Kerbin SOI all went wrong, every maneuver I tried, it would just roll the ship as fast as it can. Reloading the ship from the space center fixed it. But the same thing happened when entering Duna SOI 3- targeting system is fluctuant, sometime the blue target will start to drift even if im still in a burn and the rocket tries to follow it off-course. I think it should lock its target until the end of the maneuver, then proceed to next target, if there is. more a request than an issue, could mechjeb keep its settings, why do we have to set up autostage and attitude controls every launch? If id keep only one mod, it would be mechjeb tx alot to work on it
